The Green Light Optimal Speed Advisory (GLOSA) system allows cars to communicate with traffic lights to inform the driver of the optimum speed they should be travelling as they approach junctions or signals.

Adoption of the technology could not only reduce congestion but also improve air quality as stop/start traffic and harsh acceleration or braking near lights can have a detrimental effect.

The idea behind the technology is to "create free-flowing cities with fewer delays and less commuter stress."

Jaguar Land Rover is currently testing the technology on the F-Pace SUV as part of a £20 million research project.

The GLOSA is sign tested alongside a number of other technologies to slash the amount of time drivers spend in traffic.

For example, Intersection Collision Warning (ICW) alerts drivers when it is unsafe to proceed at a junction.

ICW informs drivers if other cars are approaching from another road and can suggest the order in which cars should proceed at a junction.

It is also developing a technology that can inform drivers about available parking spaces in car parks and an Emergency Vehicle Warning which informs drivers of an ambulance, police car or fire engine.

Oriol Quintana-Morales, Jaguar Land Rover Connected Technology Research Engineer, said: “This cutting-edge technology will radically reduce the time we waste at traffic lights.

"It has the potential torevolutionisedriving by creating safe, free-flowing cities that take the stress out of commuting.

"Our research is motivated by the chance to make future journeys as comfortable and stress-free as possible for all our customers.”
